You've seen the e-bike light and want to expand your boundaries. Like us, you believe that nothing should stand between you and your next great ride, including big climbs, headwinds and rugged trails you wouldn't otherwise be able to explore.

A lightweight and durable Alpha Platinum Aluminium frame that fully encases a 500 Wh battery for sleek looks and protection on the trail, a new Bosch Performance CX 250-watt motor that assists up to 25 km/h and an ergonomic Bosch Purion controller. A RockShox Recon RL fork with 120 mm of travel and a SRAM SX Eagle 1x12 drivetrain.

The best Bosch mountain bike electric assist system available on a value-minded e-MTB built with durable, reliable parts. The drivetrain, suspension and components deliver solid all-around performance, so you can commute to the trailhead and then spend all day riding.

The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you’re pedalling, and has less drag when you’re not
Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
It's equipped with an external charging port for easy charging on or off the bike
The size S frame features a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames

The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It’s also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It’s a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.

Watch video

Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Going for a long ride? Rack mounts make carrying accessories a breeze.

The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.

The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.

This unique protection shield made of lightweight but robust aluminium protects the motor against stones.

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
